A arson is need il .d the niacin Izii 1133 a (i (in ti 50 sists of pmviiix 00mm opera (in mme upon the rear cross bar of the main frame 12 and is coupled therewith by a pin or bolt 3'2. The lower or inclined bar 31 is coupled with the same rear cross bar of the main frame 12 by a pin or bolt 33. From the rear end of this supplemental frame there is a rigid downwardly extending arm 34.

The vehicle drawn by the tractor, see Fig.

i 1, consists of a single wheel 35 on an axle 36 on which a bifurcated frame 37 is mounted which carries a seat spring 38 for the seat 39. The frame or tongue 37 has on its extreme front end a plate or arm L0 through which the pin or bolt 33 extends. There is also an upwardly extending arm 41 on said frame 37 which is bolted with the downwardly extending arm 3 of said supplemental frame. This connection between the rear part of the tractor frame and the frame of the vehicle drawn, thereby is readily effected and the parts are as readily separated, but when they are connected, said rear member or vehicle supports and maintains the main frame of the tractor in a horizontal position. \Vithout the attachment of said rear vehicle the tractor frame would have to be maintained horizontally by some additional support beneath it.

In Fig. 2 a mowing machine 50 is attached to the tractor frame, 'said' mowing machine being of usual type and provided with a seat 3%) for the operator and having a tongue out over and detachably connected with the rear part of the tractor in the sanie manner as the frame 37 in Fig. 1. Any other sort of vehicle or agricultural implement, such as disk barrows or any other kinds of harrows or .drags, can be hitched to the tractor in "the same manner as is here shown, and will be drawn by it and will maintain the tractor frame horizontal. \Vhen any of these agricultural "implements is coupled with the tractor frame in the manner specified, with the couplings 32 and 33 in vertical alinement with each other, it amounts to a pivotal coupling whereby each ,member of the total device is capable of horizontal oscillatory movement with reference to the other. g

The steering mechanism is as follows: A

segmental rack is secured to the main frame above or upon the bar 30 of said supplemental. frame by a downwardly extending plate 61 and bolts 6'2 going through said plate and the rear bar of the main frame 12,

see Fig. 6. There are also two vertical bolts 63, see Fig. 5, passing through said segmental rack and rear bar of the frame 12, whereby said segmental rack is very rigidly o secured in place on the main frame. Near -the"reai'- portion of said segmental, rack a. post 65 mounted upon the bar 30 of said supplemental frame at the rear of the main frame and said post is provided with an inclined bearing 66 throughwhich a steering the tractor, whatever that vehicle may conveniently reach and operate the steershaft 67 extends and it is held in place by a. collar 68. The outer end of the steering shaft has a steering wheel 69, while the inner end of said shaft carries a beveled pinion 70 which meshes with said rack. The steering shaft 67 is long enough preferably to bring the steering wheel 69 almost over the seat 39 and in convenient position for the occupant on the seat of the vehicle drawn by be, to

double because it moves to one side or the other both the rear end of the tractor frame and the forward end of the vehicle frame and thereby a very sharp turn may be effected. as for instance in turning the corner of land being, plowed, or turning around the ends of rows of corn being lowed, or tnrn ing the corner of squares of grain. or clever orgrass being cut. The mounting of the tractor on two wheels and the coupling mentioned bring about this very valuable result.

In accomplishing this result it is observed that the supplemental frame formed of the parts 30, 31 and 34, is mounted in connectionwith and forms a part of the general frame work of the tractor and although it is oscillated in harmony with the frame of the. drawn vehicle or agricultural implement, the steeringmechanism is mounted on this iiscillatory supplemental frame and hence is carriedby the tractor instead'of by the drawn vehicle or in'lplment.

Not only is the steering mechanism carried by the tractor but also the other controlling mechanism, whatever' it maybe. For illustration there is shown herein a clutch 15 for. coupling and uncoupling the engine shaft and fly wheel with the gearing for driving the propelling wheels. The

means for controlling and 'operating said clutch consists of the pedals 75', each-in the shapeof a bell crank and pivoted between its ends on a bolt 76 in the rear part of the supplemental frame. There is one pedal on each side of the steering shaft and in position to be engaged by the feet of the operator sitting on the seat 39 of the vehicle drawn by the tractor. The right-hand pedal is connected with a cable 77 which passes between a pair of horizontal sheaves 78 located upon the segmental rack 60 and running to the right-hand bell crank-lever 173, whichis fulerumed at 79 on a plate 80 and rigidly secured to the main frame oi: the tractor. From said lever 178 a cahle 81 extends to the clutch nieniher 17 see 4. so that operation of the right-hand pedal will draw the clutch 15 rearward to a disengaging position and sto the movement of the tractor. 0n the other hand. the. lefthand pedal is connected by a cable 83 passing between a pair of pulleys above the pulleys TS and connected with a hell crank lever similar to the hell crank lever 178 mounted on the plate Si) to the left of'the center of the segmental rack and connected so that operation 01' the pedal will force one a n oi the lever 85 inward and through the connecting rod 80 which runs to the clutch 15, "force said clutch into engagement with the fly wheel ll or other clutch member and thus couple such clutch arrangement so that the tract. will be driven, and the greater the pressu'e on the left-hand pedal 7 the greater Hie friction between the friction clutch inenihers and 15. A sheave of each pair 0t sheaves TS and Si are adjacent each other and the two cables pass between them and the joint hetweeu said sheaves should he concentric with the rack 60 so that the operation of said clutches can he of equal facility regard less of the relative angular positions oi the tractor and the machine drawn thereby, or in other words of the motor main frame and the supplemental frame and the parts carried thereby. lhis arrangement is one of great in'iportance for in making turns one wa} or the other; it necessary that the steering wheel 9 and the pedals always be maintained in one position relative. to the seat 39. so as to he accessible and convenient to be operated by the operator. The outer end of the steering rhaft 67 is mounted in a hearing 83 held in position by hraces 8.) and 90. The braces 89 are connected with arms 91 extending in opposite directions from the post (3''; on the supplemental frame. T he brace connected with the rear part of the bar The foregoing" parts apply to the device regardless oi the kind of implement or vehicle. drawn. The following parts adapt the device particularly for plowing. There is shown two breaking plows having beams 101 extending from a point to the real-bi" the axle of the tractor to a pointin froni oi said axle so that the draft of the plows is transmitted to the main frame ()l the plow in front of the axles. The two beams 101. see Fig. 10, are. parallel and at their forward ends: re secured to the ends of a U-shaped ha r 102. A horizontal tongue or plate 103 extends forwardly from the. U- shaped plate 102 and lies hetw'eenthe horizontal plates 101 and 305 and is connected with them hy a bolt. 1%. lhe plate 105 is secured upon the plme 10% and spaced thereas to leave a sp between then tongue .03. The tongue 30.3 is or th than said space between the plates lollowiug: means. extend down from the main iraine 1:2. see Fig. and a cranl: rod 116 is mounted on said bars the middle portion. of said crank rod he horizontal. and passing: through sia iles or eves ll? secured to the heains lill. tin each Sl\ e oi the lreanis a lair iii) is nioiined on the middle poi ion of the era rel llh and when the plow is in il's lower position. pro jects downward and at 121 is pivoted to a lever 122 which is i ulerumed at 123 in a bar 124 extending down from the main frame. This lever operated by a long iron rod 125 which extends rearwardly to a point near the operator. This gives long: leverage for operating the lever and when the Forward end is elevated, and said lever is operated suliiciently to bring itself and the bar 120 into alinement with each other, they are locked by a stop block 126 on the lever against whi ii the end of the bar lillabuts. The lowered and elevaied Fi lror guiding the tractor accurately while plowing so that one wheel of the tractor will always run in the furrow, there is provided in advance of the tractor a guide plate 130 which vertical and beveled in its orward end and rigidly secured to two hliars ll which extend to the two bars 1 respectively. see lic il with w h "l r he guide plate 130 runs in a furrow and n held ixoin escape hf; the

sides ot' the furrow a d slides ah on the furrow by gravity. 1' is elevated out of the furrow when desired hy the rod 132 engaging one of the brace rods 131 and connected with a lever 133 fulcrunied on a plate 13%: extending down from the main frame 12. Said lever, in turn, is actuated by the link L35 which connects its rear end with an arm 13 secured to the side of one of the. plow beams so that as the plow heains during,' the elevation of the plows, the guide 130 will be elevated out of the furrow, but when the plows are let down again for plowing, the guide 130 will be automatically lowered into the furrow.

For the purpose of heveling the frame to allow one-wheel to travel in a furrow, the

are tilted axles 11 for the tractor wheels are each mounted .on the adjustable block 111, as heretofore mentioned, and'there is, a curved U-bar 137 secured to the frame 1! and surrounding said block 111 and bearing against projections 138 on said block. A shaft 139 is rotatably mounted near the opposite end of the block from the axle 11 and to said shaft a sheared wheel 14:0 and a ratchet wheel 141 are secured ancl'the projecting outer end of the shaft is squared so that a wrench may be applied to it for turning the same and winding or unwinding a cable 142 on said sheaved wheel, the other end of said cable being secured to a bolt 143 extending across the U-bar 137 above the block 111. A

pawl 14 k on'the block 111 is adapted to en- 7 gage the teeth of the ratchet 141 and prevent it from turning. By this means the frame may be raised or lowered, as desired.

\Vhile the main frame shown herein is rectangular and otherwise peculiarly-shaped and formed, still the invention is not limited to such main frame or to any particular kind of main frame, but to any structure carried by the wheels of the tractor and which carries the motor. Nor is it necessary, although it is preferable, to mountthe coupling frame to the rear of the tractor wheels and the invention is not limited to'any particular connection of the coupling frame.
